Finding Max Value in Python 3 Dictionary, List, Tuples, Shapefile (SHP) using FIONA

I have this code:

------------------------------------------

import fiona import pprint

c = fiona.open('C:/Users/root/Python/mi_airports.shp', 'r')

filtered = list(filter(lambda f: f['properties']['COUNTY']=='Ingham', c))

pprint.pprint(filtered)

------------------------------------------------------

The above code will output this:

Any idea how I can find the maximum/highest value for ELEVATION for that data? The output should be like this:

Airport Name: Elevation:

Thank you in advance.
